RADIATOR.

SPECIFICATION forming part ofLetters Patent No. 355.216, dated December 28, 1886.

Application tiled February 19,1886. Serial No. 192,402. (No model.)

To all whom it may concern.-

Be it known that I, CLARENCE E. Snrronn, of Lancaster, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specilication.

This invention relates to improvements in that class. of radiators which consist of a series of vertical sections connected at their top and bottom, through which the steam or other heating agent circulates.

They object of my invention is to improve the construction of this class of radiators, whereby a greater radiating` or heating surface is presented to the apartment to be heated withoutl materially increasing the size of the radiator.

The invention also relates to improvements in the-"construction of the coupling-tubes, whereby'the sections are secured together.

The invention consists, to these ends, of the improvements which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l represents a side elevation, partlyin section, of my improved radiator. Fig. 2 is a vertical crosssection of the same. Fig. 3 is a horizontal crosssection in linexfr, Fig. l, on an enlarged scale. Fig. 4 is an end view of the lower portion of one of thesections on an enlarged scale. Fig. 5 is a fragmentary sectional elevation,on an enlarged scale, showing the manner of connecting two sections together. Fig. 6 is a side elevation, on an enlarged scale, of one of the coupling-tubes. Fig. 7 is an end view thereof. Fig. 8 is an end view of one of the couplingtubes slightly modified.

Like letters of reference refer to like 'parts in the several tigures.

A A A2 represent the vertical radiatorsec- 4o tions, each of which consists of a hollow base portion, a, having a curved or semicircular bottom, a', a top chamber, b, and a series of vertical radiating-tubes, C, connecting the top and base chambers and cast in one piece there- 45 with. The vertical tubes C form a communication between the base and top chambers of each section, and the tubes C of each section are connected between the top and base portions by short horizontal tubes d. The short 5o horizontal tubes d form braces which strengthen the vertical radiating-tubes C, and also form couplings G are provided on their inner surcomlnunications between the series of tubes C of each section.

The radiating-tubes C are attcned or elongated in cross-section, as shown in Fig. 3,and the flat or-'wide sides of the two outer tubes of each section form the sides ofthe radiator. By arranging the radiating-tubes C in this manner a much larger radiating surfaceis presented to the apartmentto be heated than when the tubes 6o are arranged with the narrow ends outward, thereby increasing the outer radiatinglsurface f of the radiator.

The chambers a and b of each section are provided with threaded openings e, which are formed on opposite sides ofthe chambers and in line with each other.

f are annular shoulders or anges formed on opposite sides of the chambers a and Z, and sur rounding the openings e.

G represents screw-threaded couplings which connect the several sections together, and which are screwed into the openings rIhe couplings G are each provided with external right and left hand screwthreads g g', which 75 are separated by an annular groove, '92, de-

pressed below the screwthreads, as shown in Fig. 6. This groove facilitates cutting the right and lefthand threads, enables the radiatorsections tolbe drawn closely together, and accommodates a suitable packing between the sections. rlhe couplings G are hollow, and form a communication between the respective chambers c and b of the several sections. The

face with inwardly-projecting lugs h, having 5 straight ortlat faces h', whereby the couplings can be readily turned in the openings e by inserting a wrench or other suitable tool, I, into the bore of the coupling. The screw-threads in the two adjacent openings e of the several sections correspond with the screw-threads formed on the couplings G, one being a right hand thread and the other a left-hand thread, so that when a coupling is arranged between the'two adjacent openings, as shown in Fig. 5, and the wrench I inserted in the bore Aof the4 coupling, the latter can be readily screwedinto the openings e e 'of the two sect-ions by turning the wrench. The couplings G are screwed into the openings e until the shoulders o'r flanges f of the two adjacent openings abutagainst each IOO other, whereby a perfectly-tight joint is for-med between the two adjacent sections and the sections firmly secured together. If desired, a

suitable packing may be inserted between the through the radiator.

ianges or shoulders f. The bore of the couplngs G may be of any suitable or desirable shape that will permit'their being turned by inserting a suitable tool or wrench. Constructing the couplings G with flat sides, or of any other irregular shape that will permit them to be turned, as described, enables the sections to be secured together at their top and bottom without disturbing the position of the sections, and also enables the sections to be readily'disconnected when desired. y

Vhen the sections have been secured together, they are supported in a vertical position upon legs J, which are cast or formed on the two end sections, A A2, which are alsoprovided with the inlet and outletpipes 7c k, respectively, through which the hot water or other heating agent employed circulates The bore in the coupling G, which connects the bottom chambers Vof the end section A and the adjacent section, A, is provided with a partition, Z, which closes the communication between the two lower chambers of these sections, and causes the heatin g agent employed to be deflected upl ward in the end chamber A, through the vertical radiating-pipes C,to the top chamber, b, and through the top chambers in the remainingl sections and downward through the vertical radiating-tubes C until it escapes through the outlet-pipe k' in the bottom chamber of the end section A2. The tops of the several sections are covered by an ornamental top plate, M, which is secured to the end sections, AA', by bolts m.

I claim as my inventionl. The combination, in a radiator, of a series of vertical sections, A, each composed of a bottom chamber, a, a top chamber, b, and vertical radiating-tubes C, made oblong in cross-sec tion and connecting said top and bottom chambers, and arranged with their flat or wide sides outward, and horizontal tubes d, connecting the vertical tubes C between the bottom and top chambers, substantially as set forth.

2. In a radiator, the combination, with two --radiating-sections, of a hollow coupling, G,

provided on its outer side with right and left lholding-surfaces for the reception ofa wrench,

substantially as set forth. n

Witness my hand this 10th day ofllebruary,
